Consequently, Galen had to resort to the dissection and vivisection of animals, particularly barbary apes and pigs, as Aristotle had done centuries earlier for the study of anatomy and physiology. Galen, like others, reasoned that animal anatomy had a strong conciliance with that of humans. [13]
[11] There were very few specific words associated with either male or female anatomy at the time of Galen. The ancients "regarded organs and their placement as epiphenomena of a greater world order". [11] The absence of words associated with female anatomy shows that people did not want to see a difference between the male and female body. [12]
Testing for a malformed vein of Galen is indicated when a patient has heart failure which has no obvious cause. [9] Diagnosis is generally achieved by signs such as cranial bruits and symptoms such as expanded facial veins. [4] The vein of Galen can be visualized using ultrasound or Doppler. [4] A malformed Great Cerebral Vein will be ...
The length of the great cerebral vein of Galen varies from 0.15 to 4.2 cm (mean 0.93 cm). [4] The veins of the brain have very thin walls and contain no valves. They emerge in the brain and lie in the subarachnoid space. They pierce the arachnoid mater and the meningeal layer in the dura and drain into the cranial dural venous sinuses. [3]
Galen produced more work than any author in antiquity, [1] His surviving work runs to over 2.6 million words, and many more of his writings are now lost. [1]Karl Gottlob Kühn of Leipzig (1754–1840) published an edition of 122 of Galen's writings between 1821 and 1833.
The rete mirabile is an essential [8] part of the system that pumps dissolved oxygen from a low partial pressure of 0.2 atmospheres into a gas filled bladder that is at a pressure of hundreds of atmospheres. [9]
The anatomy part in Kitab Al-Ma'nsuri has 26 sections, being divided into sections about structures, such as bones, nerves, muscles, veins, and arteries, and organs such as the eyes, nose, heart, and intestines. He followed Galen in many of his anatomical descriptions, but also opposed—and improved—Galen's descriptions in many others.
Galen, the prominent Greek physician, surgeon and philosopher in the Roman empire, had written on anatomy among other topics, but his work remained largely unchecked until the time of Vesalius. The Fabrica rectified some of Galen's worst errors, including the notion that the great blood vessels originated from the liver.
